I have been scanning some old 35mm slides and a few have serious color damage. Just wondering if the color in this slide scan can be corrected

Re: Can the Color Be restored
Phil,this might get you at a starting point!
I totally experimented by converting to LAB as per this thread.
The black and grey points happen to be the same, at the darkest part of crotch. White point is to the right of his head in the narrow band. A bit of tweaking with adjustment layers and finished with a pass through Imagenomic Noiseware (masked) -
Re: Can the Color Be restored
Set colour samplers on the known blacks and whites and use curves to balance the RGB values; channel blending in LAB mode in various blend modes; paint with colour; Selective colour adjustments with a mask; sharpen.Comment

Re: Can the Color Be restored
Hi Philbach
The data in the Green and Blue channel is pretty messed up so detail is lost.
The Red channel however is pretty good.
One avenue to consider is just take the grayscale of the Red Channel, adjust the tone and then paint the colors you want as an overalay with blend set to Color.
Image below is an example where I colored in just a couple items. Just one path to consider.
Hope that helps

Re: Can the Color Be restored
Great work John Gary and OldBaldy.
I am guessing your scanner does not have digital ROC setting - sometimes I find that setting on my scanner works for very strong colour casts with slides that have deterioated like this. There used to be a plugin available for those without scanners that have this (CTein mentions it in his book) but don't know if its still available or where from. Probably have to check out his new book!Comment

Re: Can the Color Be restored
Well I use a an Epson v850 flatbed scanner. And I use Vuescan software. I have neutral settings on the scans that I make and use photoshop to correct color. In RGB mode the Green and Blue Channels are just about black. So its difficult to restore the color. However a nice black and white photo and be constructed. And colorization then needs to be done.Comment

I've run into this problem with many color photos dating back to the 60s/70s where there is a yellowing that shows up most in the blue channel. It would seem there would be an "easy" way to isolate this yellowing (mold?) and remove it, but I haven't found anything but cloning solutions which...11-20-2004, 03:37 PM -

Hi Folks,
Seems we have kind of a lull in images to work on so I thought I'd throw this one in. I've been thinking about it for a while anyway as this color is absolutly impossible to fix (for me anyway). I've tried every trick inthe book and I never get it quite right. Center female is my Mom....05-06-2008, 02:29 AM -
Hi there
This will be the first time ive asked for help. I have this large group shot that has faded. It has lost yellow and greens leaving mostly cyan and red.
